Instruction Sheet
Preface
Congratulations on your purchase of DELTA's brake module. BUE brake
units are applied to absorb the motor regenerative energy when 3-phase
induction motor stops by deceleration. With BUE brake unit, the
regenerative energy is dissipated in the brake resistors. To prevent
mechanical or human injury, please read this instruction sheet thoroughly
before wiring.
BUE brake units are suitable for VFD-E/VFD-EL Series. BUE brake units
need to be used in conjunction with BR series brake resistors to provide the
optimum brake characteristics.
BUE brake units (20015 and 40015) are approved by Underwriters
Laboratories, Inc. (UL) and Canadian Underwriters Laboratories (cUL). The
content of this instruction sheet may be revised without prior notice, please
consult our distributors or download the most updated version at

Note1: When the AC drive uses with DC reactor, please refer to the wiring diagram in the
VFD-E/EL user manual for wiring terminal +(P) of brake unit.
Note2: DO NOT wire terminal -(N) to neutral point of power system.
NOTE
For safety consideration, install an overload relay between the
brake unit and the brake resistor. In conjunction with the magnetic
contactor (MC) prior to the drive, it can perform complete protection
against abnormality.
The purpose of installing the thermal overload relay is to protect the
brake resistor from damage due to frequent brake, or due to brake
unit keeping operating resulted from unusual high input voltage.
Under such circumstance, just turn off the power to avoid
damaging the brake resistor.
Please refer to "7 Brake Resistor/Units for the AC Drives" for the
specification of the thermal overload relay.
Wiring Warnings
Do not proceed with wiring while power is applied to the circuit.
The wiring gauge and distance must comply with the local
regulations.
The +(P), -(N) terminals of the AC motor drive (VFD-E/VFD-EL
Series), connected to the brake unit (BUE), must be confirmed for
correct polarity lest the drive and the brake unit be damaged when
power on.
When the brake unit performs brake, the wires connected to +(P),
-(N), B1 and B2 would generate a powerful electromagnetic field
for a moment due to high current passing through. These wires
should be wired separately from other low voltage control circuits
lest they make interference or mis-operation

Inflammable solids, gases or liquids must be avoided at the location
Power Input Terminal
where the brake resistor is installed. The brake resistor had better
be installed in individual metallic box with forced air-cooling.
Power lamp
Connect the ground terminal to the Earth Ground. The ground lead
Brake lamp
must be at least the same gauge wire as leads +(P), -(N).
Fault lamp
Please install the brake resistor with forced air-cooling or the
equivalent when frequent deceleration brake is performed (over
Dip Switch
for Input Voltage Setting 10%ED).
To avoid personal injury, do not connect/disconnect wires or
regulate the setting of the brake unit while power on. Do not touch

the terminals of related wiring and any component on PCB lest

Brake Unit
The Voltage Settings
The power source of the brake unit is the DC power from the + (P) and - (N)
terminals of the AC motor drive. Therefore, it is an important step to set the
voltage by the input voltage of the AC motor drive before operation. This
setting will affect the voltage level of the brake unit.

NOTE
Before setting the voltage, make sure the power has been turned
off.
Please set power voltage as the possible highest voltage for
unstable power system. Take 380VAC power system for example.
If the voltage may be up to 410VAC, 415VAC should be selected.
For VFD-E/VFD-EL Series, please set parameter Pr06.00=0 (Over
Voltage Stall Prevention) to disable over-voltage stall prevention, to
ensure stable deceleration characteristic.
